, An important object of this invention is the productionof areceptacleby a method that is inexpensive and that will effect great strength of the receptacle even though some of the material used in itsmaiultacture may be. in itself, previousto its incorporation in the product, incapable of withstanding great strains. 1 j

Another obj set is to "so wind "and arrange strip-material such as paper or other fibrous material as'ito produce receptacles 10f mar and minimum liability to leak.

1 Another obj ectis' to so arrange strip" ma- 1 terial in layers as to produce maximum smoothness of the 1ns1de @Ll'ltjhOHlZSldGSllPw faces of thereceptacles. 1

Thus the compound is spread; on the under surfaces of the strips 10, 11, 13 bythe distributing roller 20,

thestripspass over said roller.

The strips; 10, I1,L13,are threaded from 1 theidistributing roller :20 overa guideroller 22 rotatably mounted on' the feeder arm 17. The-rollers 12, 14,15, 22 may be provided with flanges 23-to prevent the edgesEof adjacentstripsioverlapping one another;

The shaft .49 l operatesa collapsible core of 1 suitable construction and in the instance shown,- said- ,core comprises heads; 54, 55 and an intermediate barrel shaped core-body formed of longitudinally curved segments 56,57 which arepivoted at 58,59 to arms 60, 61 respectivelythatzare pivoted fat 62 -;to hubs 63; fa stened. by. keys-164e- I 'or" the "like to the sl1aft. :t9 ,-said1arms- 61 being sectional and .provided with knuckle joints 65.-

Thegnethodjs.carried out on the machine above described as follows:

The tank 21 will be provided by theate tendant with a suitable binding compound such as glue, silicateof. sodas and nlum and the spindles 7 will be supplied with spools of strip material such as paper or the like and the strips 10,11, 13 will be threadedro engage the, guide: rollers 12,. 14, '15 and 22, T-he1leven19 willbe operated to raise the roller. 15, thus to hold the strips 10,1 11,113

Assuming at the start that the feed arm is in .sueh'position.that thev roller 22 is di rectlyover theihead :54, the freeuends of the strips 10, 11, 13 will be fastened under thespring clip 78 and l3l1(5.1111(3 l1l116-Will then be started "into voperation by turning ,the

driving. (pulley 52.. by. a :powerdriven \belt, not shown, so aseto turn .the coreuin the direction of the large feathered arrow 81, Fig. 1, to ind the strips with abutting. edges in helicalhturns progressing toward, thehead 55 to .formuan .inner layer hen. the team. shaft has rotated sutlioientlyto swinzgthe feed arm .farxenonglrisd that. the upper end diagonally crossingthe-turns. of the-first layer a, tlrusiforming a second coated layer Z2 bound by the glue to the first layer.

Thus the gfeedarm is c'aused to swing to and froto Wind the-stripmaterialto and fro around the form as the core revolves nd the winding operation "i ontinued untilj any desired number ,of-layershave been wrapped on the coreto forms tubularbody, the e being five layers a, 7), 0, (1, 6 fornnng the tubular body, shown -in;,Figs. 7 and 8. When the desired l111ml G1"0f' layers have been formed, the operator will sever the un- Wound portions ;of the strips 10, "11', 13- from thewoundportions thereofand he will then operate thgarms-Glgtobend the sameat the knucklejointsto cause thesegment 57 to be drawn radially inward toward the shaft 49. This may be done by the operator passing his arm into the interior of th core through one of the openings in the head 54, see Fig. 1; or any suitable mechanism, not shown, may be connected to the arms 61 whereby to bend them. The operator will then grasp the tubular body and pull the same forward together with the head 79 away from the head 54, thus causing the arms 60, 61 to swing forward and the segments 56 to collapse inward alongside of the segments 57 so as to free the tubular body from the core.

The wound strips 10, 11, 13 will then be trimmed off by hand or otherwise to leave tongues 82 at both ends of the tubular body,

- of the head 79, thus securely fastening said head in place and strengthening the endof the receptacle.

If it is desired to have heads at both ends of the receptacle, a second head will be creasing in diameter from one end ofthe core to the mecllan portlon of the core and fastened in place at the other end of the receptacle in the same way as just described for the head 79, nd if it 1s not desired to have a secondhead, a rim analogous to the rim 83 will be fastened in place at said other end of the receptacle, the duplicate constructlonbeing obvlous wlthout it being necessary to more fully show and describe said construction.

It is noted that by WlIldlllgi the strlp ma terial in one direction in hellcal turns indecreasing in diameter fromsaid median portion to the opposite end of the core the endwiSe crushing strength of the receptacle is maximized, for if the strips were wound to form a straight tube the walls would crush under. considerably less force than would be required to crush the receptacle having the bulge to its walls s provided for by my method.

I claim:

1. The method of making receptacles,

which method comprises holding a head against a core, winding strip material over the core and around the head in one direction in helical turns increasing in diameter from one end of the core to the median portion of the core and decreasing in diameter from said median portion to the opposite end of the core to form a layer, then winding saidstrip material in the opposite direction to forma second layer over the first layer,

and then fastening the head to both of said layers;

2. The method of making receptacles, which method comprises holding a head against a core, wrapping strip material spirally in superposed layers around the periphery of the core and head so as to extend beyond the outer face of the head to form an annular tongue, separating the head and body from the core, and then fastening a grooved rim over the tongue and tothe head to hold the superposed layers and head together.

3. The method of making receptacles, which method comprises placing a head against a core, wrapping strip material spirally to and fro in superposed layers and continuous from layer to layer and beyond the outer face of the head so as to form an annular tongue composed of layers of the material, inserting all of the layers of the tongue in a grooved rim, and then fastening the rim to the head to hold said layers and head together. 7

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 24th day of March, 1915.
